A surface-protective coating forming composition exhibiting excellent shelf life (storage stability) and cured coating performance is derived from alkoxysilane and a plurality of metal oxides.
A layered structure comprising in sequence a substrate, a scratch-resistant layer and a covering layer is disclosed. The scratch-resistant layer contains an at least partially cured polycondensate of a first reaction mixture that contains at least one silane, and the covering layer contains a cured polycondensate of a second reaction mixture that contains a silane compound having at least one non-hydrolyzable substituent that carries an epoxy group. The invention finds applicability for the uniform coating of three-dimensional substrates, especially motor vehicle windows.

A process for the production of a layer system that is non-fogging and scratch resistant is disclosed. The layer system includes a substrate (S), one or more scratch-resistant layers (SR) and a non-fogging top layer (T). The process entails (a) applying one or more of at least partially cured coating composition to the substrate (S), the composition comprising a sol-gel produced polycondensate based on silane, to form a scratch-resistant layers (SR) and (b) subjecting the surface of the exposed scratch-resistant layer (SR) to flaming with simultaneous deposition of a layer which substantially comprises a compound of silicon, aluminium, titanium, indium, zirconium, tin and/or cerium to produce a non-fogging top layer (T).
